Once the initial measures are completed, participants will be scheduled to begin the allocated treatment based on group assignment. Group 1 will receive RSWT to the most painful spot within each of the 3 most painful regions, while group 2 (placebo) will receive a similar treatment but a soft rubber cap will be applied to the applicator, leaving air between the transmitter and the cap and the participant's skin. Treatments will be spaced one week apart over a 5 week period of time and will occur at Lakehead University's School of Kinesiology, room SB-1028.
